DECOMPRESSION MODEL The programs within the Duo Advance simulate the absorption of nitrogen into the body by using a mathematical model. This model is merely a way to apply a limited set of data to a large range of experiences. The Duo Advance dive computer model is based upon the latest research and experiments in decompression theory. Still, using the Duo Advance, just as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding decompression sickness, i.e. “the bends.” Every diver’s physiology is different, and can even vary from day to day. No machine can predict how your body will react to a particular dive profile.

NOTICE STORAGE and INITIAL ACTIVATION
Duo Advance Watch/Dive Computers are placed in a Deep Sleep mode prior to being shipped from the factory. The intent is to extend storage life of the Battery for up to 7 years, before the unit is initially placed in service. In this mode, Date and Time are updated as they normally would be. However, they are not displayed. Upon waking the Duo Advance up, the correct Date and factory Time will be displayed and it will be ready to operate with full functions. To wake the Duo Advance up from Deep Sleep mode, simultaneously depress the upper/right (S) and lower/left (A) buttons for 2 to 3 seconds until the display comes full ON displaying the MAIN TIME screen, then release them. NOTE: Once the Duo Advance is brought out of the Deep Sleep mode, it can only be placed back in it by the factory.

INTRODUCTION and GENERAL FEATURES AND DISPLAYS
9
introduction Welcome to Bism and thank you for choosing the Duo Advance ! It is extremely important that you read this Operating Manual in sequence and understand it completely before attempting to use the Duo Advance as a dive computer. Remember that technology is no substitute for common sense, and a dive computer only provides the person using it with data, not the knowledge to use it. INTERACTIVE CONTROL CONSOLE The Interactive Control Console consists of four Control Buttons that allow you to select mode options and access specific information. They are also used to enter Settings, access Log and History modes, activate the Backlight, and acknowledge the Audible Alarm. Throughout this manual they will be referred to as the M, S, L, and A buttons. • • • •

OPERATING MODE STRUCTURE Unless it is operating in Dive Computer mode, the Duo Advance will be ON in the default WATCH MAIN TIME (home time) mode (Fig. 1), like a standard WATCH, until the Mode is changed. The M button is used to access 4 other Modes that include Alternate Time Mode, Countdown Timer, ChronoGraph (stop watch/lap timer), and Daily Alarm. It is also used to revert to the Local Default Time display and access Computer Modes. The screens of the Main Modes and Sub Modes will remain on display until a button is pressed to access another screen or Mode, activate a sequence, or for 2 minutes if no button is pressed. The ChronoGraph remains on display as long as it is running unless another Mode is accessed.

When Wet Activation is set On, the Duo Advance will enter selected Dive Mode upon descent to 5 FT (feet)/1.5 M (meters) for 5 seconds, regardless of what operating Mode it is in. WARNING: When Wet Activation is set OFF, the Duo Advance must be in Dive Surface Mode (NORM< GAUG, or FREE prior to the first dive of a new series. Commencing a dive while in Watch modes will not activate Dive Mode unless Wet Activation is set ON.

Once a dive is made in GAUG Operating Mode, the Duo Advance is locked into that Mode for 24 hours after the dive. PC INTERFACE Interface with a PC is accomplished by connecting the Duo Advance to a PC USB Port using the Bism PC Interface USB cable. The same Cable is used for Upload and Download. The software program is on the Bism CD, together with a USB Driver. The program's Help serves as the user manual and can be printed for personal use. The Settings Upload program is used to check the Duo Advance's existing Settings and for entering Time, Alarm, and Dive Computer settings into the Duo Advance.
The Data Download program is used to retrieve Data that was sampled during dives and stored in the Duo Advance's memory. The Duo Advance checks for an External Access request once every second while in the Watch Main Time. Checks are not made if the unit is wet. For a connection to be made, the Interface Cable is clipped onto the Duo Advance's Data Port and plugged into a PC USB Port. To establish the connection, the PC program must be running. When the connection is made, all segments of the LCD appear on the display until completion of the Upload or Download operation. • The Duo Advance reverts to the Watch Main Time screen after completion of the Upload or Download operation, or after 2 minutes if no PC action was taken. SYMBOLS AND ALPHA NUMERIC GraphICS The upper line of digits on the LCD screen is used to convey alpha Messages such as Day of the Week, Operating Modes, items being Set, Altitude level, and Alarm identification. At times, the second line is also used to display alpha numeric Graphics such as FO2 and On/Off. The PO2 values will appear in the lower line. audible alarm Most warning situations that activate the Audible Alarm while operating in NORM or GAUG Mode cause the Duo Advance to emit 1 beep per second for 10 seconds, or until the situation is corrected, or it is acknowledged by momentarily pressing and releasing the S button (less than 2 seconds). After being acknowledged and the situation corrected, the Alarm will sound again upon reentry into the warning situation, or entry into another warning situation. 13
FREE Dive Mode has its own set of Alarms which emit 3 short beeps either 1 or 3 times which cannot be acknowledged or set Off. An LED Warning Light, located on the side of the housing, is synchronized with the Audible Alarm. It will flash as the Audible Alarm sounds. It will turn Off when the Alarm is acknowledged or the situation is corrected. The Audible and LED will not be active if the Alarm is Set OFF (a group A setting). Situations that will activate the NORM/GAUG 10 second Alarm include • Descent deeper than the Max Depth Set Point selected. • Dive Time Remaining at the Set Point selected. • Elapsed Dive Time at the Set Point selected. • High PO2 at the Set Point selected. • High O2 of 300 OTU (single or daily exposure). • Nitrogen Bar Graph at the segment Set Point selected. • NORM/GAUG Ascent Rate exceeds 60 FPM (18 MPM) when deeper than 60 FT (18 M), or 30 FPM (9 MPM) at 60 FT (18 M) and shallower. • Entry into Decompression Mode (Deco). • Conditional Violation (above a required Deco Stop Depth for less than 5 minutes). • Delayed Violation (above a required Deco Stop Depth for more than 5 minutes). • Delayed Violation (a Deco Stop Depth greater than 60 FT/18 M is required). • Delayed Violation (Max Operating Depth of 330 FT/100 M is exceeded). • Watch Daily Alarm reaches time set (disabled during Dive Modes). • Watch Mode Countdown Timer reaches 0:00.

POWER SUPPLY The Duo Advance utilizes one 3 volt CR2430 Lithium Battery. When used as a Dive Computer, the battery should operate normally for 1 year or 300 dive hours if 2 dives are conducted during each dive period. The Duo Advance checks its battery voltage every 2 minutes during surface operation. • If voltage decreases to the Warning level (2.75 volts), the Battery icon will appear on Surface display screens (Fig. 3a) as an indication that the Battery should be changed prior to commencing a series of dives. • If voltage decreases to the Alarm level (2.50 volts), the Battery icon will flash and the message CHNG > BATT will scroll at the top of the display (Fig. 4). Operation will automatically revert to Main Time Mode. The Duo Advance would then only operate in Watch modes until the Battery becomes completely depleted. • Low Battery Warning/Alarm conditions are not displayed during Dive Modes. • If a Low Battery condition was not displayed prior to starting a dive, and a Low Battery condition occurs during the dive, there will be sufficient Battery power to maintain operation for the remainder of that dive.

bar Graph The Duo Advance features one shared Bar Graph that represents either nitrogen loading, or when accessed, oxygen accumulation. By default, the Bar Graph (Fig. 23a), referred to as the Nitrogen Bar Graph (NIBG), represents your relative no decompression or decompression status. Fig. 23 - NIBG
As your Depth and Elapsed Dive Time increase, segments will add to the NIBG, and as you ascend to shallower depths, the segments of the NIBG will begin to recede, indicating that additional no decompression time is allowed. The Nitrogen Bar Graph monitors 12 different nitrogen compartments simultaneously and displays the one that is in control of your dive. It consists of 5 segments, the left 4 represent No Decompression status and the fifth at the right indicates a Decompression condition. a
Fig. 24 - O2BG
32
When the Duo Advance is set to operate in NORM Nitrox mode, the Bar Graph will represent oxygen accumulation when the O2 data screen (Alternate Display) is accessed temporarily. The Graphic O2BG will appear as an indication (Fig. 24a). Regardless of which parameter the Bar Graph is representing at the time, nitrogen (if NORM or FREE) and oxygen (if NORM) calculations will continue to be performed in the background.
Displays associated with oxygen and the O2 Bar Graph will be displayed if FO2 has been set at a value other than 'Air' (e.g., a numerical value) and the Alternate screen that displays oxygen related data is accessed. When the oxygen data screen is accessed during a NORM dive, the Bar Graph will show the maximum of either per dive accumulated oxygen or 24 hour period accumulated oxygen. As your oxygen exposure (accumulation) increases during a NORM dive, segments will add to the O2 Bar Graph, and as saturation decreases, it will begin to recede, indicating that additional exposure is allowed for that dive and 24 hour period. The Duo Advance will store oxygen accumulation calculations for up to 10 dives conducted during a 24 hour period. If the maximum limit for NORM dive oxygen loading has been exceeded for that day (24 hour period), all of the segments of the O2 Bar Graph will be displayed flashing (Fig. 25). Depth/Time values will not appear in Plan Mode until the O2 Bar Graph recedes into the normal zone (4 segments) indicating that your daily oxygen dosage has decreased an amount equivalent to the amount accumulated during the latest dive completed.

Fig. 26 - CURRENT DEPTH
While you cannot provide a guarantee against the occurrence of decompression sickness, you may choose your own personal zone of caution based upon age, physique, excessive weight, etc., to reduce the statistical risk. Within the available NORM mode parameters that can be set (described later) are a NIBG alarm and a Conservative Factor which if set On reduces No Decompression times allowed. ALPHA / NUMERIC displays Depth Displays (all Modes) During dives, Current Depth (Fig. 26a) and Max Depth, which is accessed as an Alternate display (Fig. 27a), indicate Depths from 0 to 330 FT (100 M) in increments of 1 FT (0.1 M).
a
During a No Decompression Safety Stop, the set Stop Depth is displayed and during Decompression, the required Stop Depth is displayed. Time and Date Displays Time of Day and NORM/GAUG mode displays are shown in hour:minute format (i.e., 1:16 represents 1 hour and 16 minutes, not 116 minutes!).
Fig. 27 - MAX DEPTH
34
FREE Dive Mode times are shown in minute:second format.
a
The colon that separates hours and minutes (or minutes and seconds) blinks once per second when the display is indicating real time (e.g., Surface Interval, Elapsed Dive Time), and is solid (non blinking) when times are calculated projections (e.g., Time to Fly, Plan). The Primary Time display is located in the middle row of the display (Fig. 28a). Another time display (Fig. 28b) is located in the lower row. Both displays are identified by the symbol TIME.
b
Fig. 28 - TIMES
When the Duo Advance is operating in Dive Computer mode, Date is displayed only to identify dives when they are accessed in the Log mode. Month appears to the left of Day (Fig. 29a) separated by a decimal point (month.day).

DIVE COMPUTER SURFACE SEQUENCE AND OPERATING MODES 37
DIVE COMPUTER (DC) OPERATING MODES The Duo Advance features 3 selectable DC Operating Modes • NORM >> for normal Air or Nitrox scuba dives. • GAUG >> for scuba dives with no nitrogen/oxygen calculations. Once a dive is made in GAUG Mode, dive computer operation is locked into GAUG Mode for 24 hours after the dive. • FREE >> for breath hold dives with no scuba. SURFACE MODE Depressing M (2 seconds), while the Watch Default Time is displayed (Main or Alternate, whichever was selected as the default) accesses the previously selected Dive Mode Surface Main screen (NORM, GAUG, or FREE). If no dive has been conducted within the past 24 hours, the NORM SURF MAIN will appear as the default display indicated by the graphic NORM (Fig. 31).
Fig. 31 - NORM SURF MAIN ( no dive made)
38
• The GAUG or FREE SURF MAIN screens can be accessed by subsequent 2 second presses of M. Upon access, their graphics will flash indicating that they can be selected as the operating dive mode. • To select a mode for diving, press M (< 2 seconds) while that graphic is flashing. When the graphic becomes solid, that mode is then selected for the type of dives to be conducted.
• The operating mode selected (NORM, GAUG, or FREE) will remain on display for 2 hours until a dive is made or Watch Mode is selected. If a dive has been conducted within the past 24 hours, the SURF MAIN screen for that operating mode (NORM, GAUG, or FREE) will be displayed. At any time while operating in Surface Modes, the Duo Advance will enter Dive Mode upon descent to 5 FT (1.5 M) for 5 seconds. • During the 2 hour pre dive surface period, if M is pressed to access other screens in the Watch Mode sequence, Surface Mode must again be accessed prior to the first dive of a series (if Wet Activation is set Off ). • When Wet Activation is set On, the wet contacts will activate the selected dive mode regardless of what mode the Duo Advance is operating in at the time of the descent. The Duo Advance will enter Post Dive Surface Mode following a dive upon ascent to 2 FT (0.6 M) for 1 second. The SURF icon will flash during the first 10 minutes after a NORM/GAUG dive (Fig. 32), or 1 minute after a FREE dive. During the first 10 minutes after a dive, the SURF MAIN screen for the operating mode selected prior to the dive (NORM, GAUG, or FREE) remains on display.

Setting FO2: For each value of FO2, the Maximum Operating Depth (MOD) that can be achieved for the PO2 Alarm set will be displayed. When the FO2 Default is set On and FO2 is set for a numerical value, 10 minutes on the surface after that dive, FO2 will be displayed as 50 and further dives will be calculated based on 50% O2 for oxygen calculations and 21% O2 for nitrogen calculations (79% Nitrogen) unless FO2 is set before the dive. FO2 continues to reset to the FO2 50% Default after subsequent repetitive dives until 24 hours elapse after the last dive, or the FO2 50% Default is set Off. When the FO2 50% Default is set Off, FO2 will remain set at the last value selected for that series of repetitive dives. The default FO2 setting for each new dive Period (no dive made in 24 hours) is Air. When FO2 is set for Air, the calculations are the same as when it is set to an FO2 of 21%. When FO2 is set to Air, it remains set for Air until it is set for a numerical FO2 value (21 to 50%). When FO2 is set for Air, the O2 Bar Graph is not displayed at any time during a dive or on the surface. PO2 values and/or warnings will not be displayed during the dive. 43
FREE Dive nitrogen calculations are based on Air and not affected by these FO2 Settings. Maximum Operating Depths affected by the PO2 limit set will not be displayed when FO2 is set for Air. Fig. 37 - SET FO2 (Air setting)
Internally, the Duo Advance keeps track of the oxygen loading so that if FO2 is subsequently set for a numerical value, the oxygen accumulation for previous Air dives will be accounted for in the next Nitrox dive (during that dive period and series of repetitive dives). Once FO2 is set for a numerical value (21 to 50%) and a dive is made, the Air option is disabled until 24 hours elapse after the last dive. The Air option will not be displayed in Set FO2 selections until a full 24 hour Surface Interval has elapsed. If FO2 is set for 21%, it will remain set for 21% for that series of dives until set for a higher numerical value.

NORM PLAN MODE
Bism strongly recommends that you review the PDPS (Pre Dive Planning Sequence) prior to every NORM dive to help you Plan your dive as required to avoid exceeding no decompression or oxygen exposure limits. This is especially important for repetitive dives when the PDPS indicates adjusted dive times that are available for the next dive, based on residual nitrogen or oxygen accumulation (whichever is in control) following the last dive and surface interval. Calculated no decompression dive times in Plan Mode are based on the FO2 setting selected. • Pressing A (< 2 seconds), while viewing the NORM SURF MAIN will access the Plan Mode Lead-in screen. • Pressing S repeatedly (< 2 seconds each time) will step through the Planned Depths from 30 to 190 FT (9 to 57 M) in increments of 10 FT (3 M), displaying the allowable no decompression dive times (NDLs).
The PDPS will stop at the Maximum Depth that will allow theoretical no decompression dive time of at least 1 minute based upon the previous dive profiles in a series of repetitive dives and taking into account descent and ascent rates of 60 FPM (18 MPM). When the Conservative Factor is set On, no decompression dive times are reduced to the values of the next 3000 foot (915 meter) higher Altitude. • Pressing A (< 2 seconds) before a dive will revert to the NORM SURF Main, or after a dive access Fly Time. 55

OVERVIEW OF DIVE MODE INFORMATION
67
Dive Time Remaining (DTR) One of the most important pieces of information on Bism dive computers is the Dive Time Remaining numeric display. The Duo Advance constantly monitors decompression status and oxygen accumulation. The Dive Time Remaining display will indicate the No Deco Time or O2 Time, whichever Time is the least amount available. No Decompression Dive Time Remaining (NDC) NDC is the maximum amount of time that you can stay at your present Depth before entering a Decompression situation. It is calculated based on the amount of nitrogen absorbed by hypothetical tissue compartments. The rates each of these compartments absorb and release nitrogen is mathematically modeled and compared against a maximum allowable nitrogen level. Whichever one is closest to this maximum level is the controlling compartment for that depth. Its resulting value will be displayed numerically along with the TIME and NDC icons (Fig. 66a) and graphically as the NIBG (Fig. 66b). a b As you ascend from depth following a dive that has approached the No Decompression limit, the NIBG segments will recede as control shifts to slower compartments.
Fig. 66 - NO DECO DIVE TIME REMAINING
68
This is a feature of the decompression model that is the basis for multilevel diving, one of the most important features that Bism dive computers offer.
The algorithm used is based upon Haldane’s theory using maximum allowable nitrogen levels developed by Merrill Spencer. Repetitive diving control is based upon experiments designed and conducted by Dr. Ray Rogers and Dr. Michael Powell in 1987. Diving Science and Technology® (DSAT), a corporate affiliate of PADI®, commissioned these experiments.

Fig. 67 - O2BG
Oxygen Accumulation Time Remaining (OTR) When FO2 is set for Nitrox, oxygen accumulation (saturation or exposure) during a dive, or 24 hour period, appears graphically as the O2BG (Fig. 67a) when the Alternate (O2) screen is accessed. As time remaining before reaching the oxygen exposure Limit decreases, segments are added to the O2BG. When the amount of time remaining before reaching the O2 limit becomes less than NDC (No Deco Dive Time Remaining), calculations for that depth will be controlled by O2. O2 Time Remaining will then appear as Dive Time Remaining (Fig. 68a) identified by the TIME and O2 icons.
a
As oxygen accumulation continues to increase, segments will add to the O2BG. Fig. 68 - O2 DIVE TIME REMAINING
69
Variable Ascent Rate Alerts associated with Ascent Rate are based upon 2 sets of speeds which change at a reference depth of 60 FT (18 M). WARNING: At depths greater than 60 FT (18 M), Ascent Rates should not exceed 60 FPM (18 MPM). At depths of 60 FT (18 M) and shallower, rates should not exceed 30 FPM (9 MPM). Ascent Rate Warning At depths deeper than 60 FT (18 M), a warning (Fig. 69) will be given when Ascent Rates exceed 50 FPM (15 MPM). The message SLOW > SLOW will scroll until the Ascent is slowed. At 60 FT (18 M) and shallower, the warning will be given when Ascent Rates exceed 25 FPM (7.5 MPM). Ascent Rate Alarm At depths deeper than 60 FT (18 M), an alarm will sound when Ascent Rates exceed 60 FPM (20 MPM). At 60 FT (18 M) and shallower, the alarm will sound when Ascent Rates exceed 30 FPM (10 MPM).
Fig. 69 - ASCENT WARNING/ALARM

The Audible will sound, the LED will flash, and the message SLOW > SLOW will scroll on/off at the top of the screen. The Audible and LED will stop when acknowledged with the S button or when the Ascent is slowed. After acknowledged, the message SLOW > SLOW will continue to scroll until the Ascent is slowed below the alarm rate.
ELAPSED DIVE TIME The maximum duration that Elapsed Dive Time will be displayed is 9 hours and 59 minutes (9:59). In the event that the Duo Advance is at depth for a greater time, it will cease operation as a Dive Computer and revert to operation as a Watch, displaying the Main Time screen. CONTROL OF DISPLAYS During dive modes, there is a Main (default) display of important information relevant to the specific mode that the Duo Advance is operating in (No Deco, Deco, GAUG, FREE, etc.). • Pressing A (< 2 seconds) will access Alternate and Secondary displays. • Depressing A (2 seconds) will access Deep Stop Preview (if triggered). • Pressing S (< 2 seconds) will acknowledge/silence Alarms. • Depressing L (2 seconds) will activate the Backlight.
> The display will be illuminated while L is depressed, then after it is released for the Backlight Duration time set (0, 5, or 10 seconds) for a maximum of 20 seconds. > The Backlight will not activate during a Low Battery condition.

WET ACTIVATION CONTACTS The Dive mode Wet Activation feature is active any time Wet Activation is set On.
Fig. 70 - WATCH MAIN TIME
The Duo Advance is configured with contacts that will automatically activate Dive mode when the space between the contacts is bridged by a conductive material (immersed in water) and it senses a depth of 5 FT (1.5 M) for 5 seconds. The contacts are the pins of the PC Interface Data Port and the stems of the push buttons. As long as the contacts are bridged on the surface, the graphic WET will alternate with the Day of Week graphic (MON, etc.) on the Watch Time screens (Fig. 70), and the graphics NORM and SEA (or EL2 to EL13) on the NORM, GAUG, and FREE Surface Main screens (Fig. 71). Upon removing the bridge between the contacts (drying the Duo Advance), the graphic WET will no longer be displayed. The Duo Advance will continue checking for depth, until a dive is made or it reverts to the Watch Time screen after 2 hours.

Decompression The Duo Advance is designed to help you by providing a representation of how close you are to entering Decompression. Decompression mode activates when the theoretical No Decompression time and depth limits are exceeded. Upon entry into Deco, the Audible will sound, the LED warning light will flash, and the graphic message DECO >> STOP will scroll each 3/4 second On and 1/4 second Off, until acknowledged or for 10 seconds.
Fig. 79 - DECO ENTRY
Once silenced, the graphics DECO >> STOP >> xxF (or xxM) will scroll each 2 seconds On 2 seconds blank. • Pressing S (< 2 seconds) will acknowledge/silence the Audible (unless it was set Off ). • The Up Arrow icon will flash (Fig. 79) if you are greater than 10 FT (3 M) deeper than the required Stop Depth. • Once you are within 10 FT (3 M) of, and below, the required Stop Depth, the Up Arrow will be removed. Managing Decompression Stops To fulfill your decompression obligation, you should make a safe controlled Ascent to a depth slightly deeper than (Fig. 80a), or equal to, the required Stop Depth indicated (Fig. 80b) and decompress for the Stop Time indicated (Fig. 80c).

The amount of decompression credit time that you receive is dependent on depth, with slightly less credit given the deeper you are below the Stop Depth indicated. You should stay slightly deeper than the required Stop Depth indicated until the next shallower Stop Depth appears. Then, you can slowly ascend to, but not shallower than that indicated Stop Depth. DECO STOP MAIN, information includes (Fig. 81) > NIBG, all 5 segments indicating Deco. > Graphics DECO >> STOP >> xxF (or xxM), scrolling. > Current Depth with FT (or M) icon. > Total Ascent Time* (hr:min) with TIME and TAT icons. > Stop Time (hr:min) required with STOP and TIME icons. > Nx icon, if FO2 is set for Nitrox. • Pressing A (< 2 seconds) will access ALT 1 (Fig. 82); then ALT 2 and Secondary, similar to the Deep and Safety Stop screens.

*TAT (Total Ascent Time): TAT (Fig. 81a) includes Stop Times required at all calculated Deco Stop Depths plus vertical Ascent Time calculated at 60 FPM (18 MPM) for depths deeper than 60 FT (18 M), and 30 FPM (9 MPM) for depths of 60 FT (18 M) and shallower.
VIOLATION MODES While in Violation modes, the Alternate and Secondary displays previously described can be accessed using the A button, the Backlight can be activated using the L button, and Alarms can be acknowledged/silenced with the S button. CONDITIONAL VIOLATION If you ascend shallower (Fig. 83a) than a required Decompression Stop Depth (Fig. 83b), the Audible will sound, and the LED and Down Arrow icon will flash until you descend below the required Stop Depth. The graphic DOWN >> DOWN will scroll until the Alarm is acknowledged/silenced, then the graphics DOWN >> TO >> xxF (or xxM) will scroll. If you descend below the required Stop Depth before 5 minutes have elapsed, the operation will continue in Decompression. b
No off gassing credit will be given while above a required Stop Depth, and for each minute above it 11/2 minutes of Penalty Time will be added to required Stop Time and TAT (Total Ascent Time). The added Penalty (decompression) Time will have to be worked off first, before off gassing credit will be given.
a Fig. 83 - CONDITIONAL VIOLATION
81
Once the Penalty Time is worked off, and off gassing credit begins, required Deco Stop Depths and Time will decrease toward zero. The NIBG will recede into the No Deco zone and the operation will revert to the No Deco dive mode.
Fig. 84 - DELAYED VIOLATION 1
Upon entry into the following Violation modes, the Audible will sound and the LED will flash even if Set OFF. When these events occur, the Alarm cannot be acknowledged/silenced by pressing the S button. DELAYED VIOLATION 1 (Fig. 84) If you remain above the required Deco Stop Depth for more than 5 minutes, the full NIBG and Down Arrow icon will flash until you descend below the required Stop Depth. The graphics DOWN >> TO >> xxF (or xxM) will continue to scroll. This is a continuation of a Conditional Violation. DELAYED VIOLATION 2 (Fig. 85) The Duo Advance cannot calculate Decompression times for Stop Depths much greater than 60 FT (18 M) and offers no indication of how much time spent underwater would result in the need for a greater Stop Depth.
Fig. 85 - DELAYED VIOLATION 2
82
If the Decompression obligation requires a Deco Stop Depth between 60 FT (18 M) and 70 FT (21 M), the NIBG will flash and the graphics DECO >> STOP >> 60F (18M) will scroll.
When this occurs, you must make a controlled Ascent to just deeper than, and stay as close as possible to, 60 FT (18 M) without causing the NIBG to flash. When the required Stop Depth indicates 50 FT/15 M, etc., you can ascend to those Stop Depths and continue decompressing. DELAYED VIOLATION 3 (Fig. 86) If you descend deeper than the MOD (Maximum Operating Depth) of 330 FT (100 M), the Up Arrow icon will flash, and the Current Depth and Max Depth displays will only indicate 3 dashes ( - - - ) signifying that you are Out of Range. The graphics TOO >> DEEP will scroll until Ascent is made above 330 FT (100 M). Upon ascending above 330 FT (100 M), the Current Depth display will be restored, however Max Depth will only display 3 dashes for the remainder of that dive. Also, the Log for that dive will display 3 dashes as the Max Depth achieved. VIOLATION GAUGE MODE If a Decompression Stop Depth much greater than 60 FT (18 M) is required, an Immediate Violation Mode will be entered. This would be preceded by entering Delayed Violation 2. The unit would then operate in Violation Gauge Mode during the remainder of that dive and for24 hours after surfacing.
Fig. 86 - DELAYED VIOLATION 3

Violation Gauge Mode turns the Duo Advance into a digital instrument without any decompression or oxygen monitoring functions. VIOLATION GAUGE MAIN, information includes (Fig. 87) > Full NIBG and Up Arrow icon, flashing. > Graphics UP >> VIOL, scrolling. > Current Depth with FT (or M) icon. > Dive Time Remaining as 0:00 (hr:min) with TIME and NDC icons. > Elapsed Dive Time (hr:min) with DIVE and TIME icons. > Nx icon, if set for Nitrox. Operation will also enter Violation Gauge Mode 5 minutes after surfacing from a dive in which a Delayed Violation occurred. Violation Gauge Mode on the Surface does not allow access to the Set F, Plan, and Desat features/screens. The countdown timer that appears when you access Time to Fly does not represent Time to Fly. It is only provided to inform you of the time remaining before normal Dive Computer operation can resume with full features and functions. Fig. 87 - VIOLATION GAUGE MAIN

High Oxygen Accumulation The O2BG displays either oxygen accumulated during that nitrox dive, or during the repetitive nitrox dives you conduct during that 24 hour period, whichever of the two is greater at that time. The O2BG allows you to monitor how close you are coming to the limits of oxygen exposure. If the theoretical amount of oxygen accumulated equals, or exceeds, the limit for a single exposure, or the exposure limit for a 24 hour period (300 OTU), O2 Dive Time Remaining becomes 0:00 (hr:min), the graphic O2BG appears and the full Bar Graph and Up Arrow icon will flash (Fig. 90). The Audible will sound, the LED will flash, and the graphics HIGH >> O2 will scroll. When the Alarm is acknowledged/ silenced, the graphics UP >> HIGH >> O2 will scroll until the level of O2 decreases below the limit. • Pressing A (< 2 seconds) will access the Alternate and Secondary screens similar to No Deco.

Upon surfacing, operation will lock in to NORM Mode until the O2BG recedes to 4 segments. Access to Watch Mode is allowed but access to GAUG and FREE is blocked.
NORM POST DIVE MODES
87
post dive surface mode When you ascend to 2 FT (0.6 M), operation will enter Surface Mode and begin counting your Surface Interval. TRANSITION PERIOD If you descend the first 10 minutes after surfacing (referred to as the Transition Period), time underwater will be considered a continuation of that dive. The time at the surface (if less than 10 minutes) will not be added as Dive Time. Transition Period information on the surface includes (Fig. 91): > NIBG. > Graphic NORM alternating with the graphics SEA (or EL2 through EL13) and WET (if wet). If a Low Battery condition occurs during a dive, the message CHNG > BATT will scroll upon surfacing. > Battery icon if a Low Battery Warning condition exists, flashing if Too Low. > Surface Interval Time (hr:min) with SURF and TIME icons. > Dive Number with DIVE icon. > Nx icon, if set for Nitrox. During the Transition Period, Alternate displays and the Log can be accessed. Other modes (e.g., Plan, Fly, Sat, Set) will be accessible after 10 minutes on the surface. Fig. 91 - TRANSITION PERIOD
88
Log Data will not be stored in the unit's memory until the 10 minute Transition Period on the surface is completed.
AFTER THE TRANSITION PERIOD Once 10 minutes have elapsed, the SURF icon will stop flashing indicating that the Dive and Transition Period are completed, and a subsequent descent will be considered a new dive. Operation will then revert to Watch Default Time. NORM SURF Main (Fig. 92) can be accessed from Watch Default Time screen by pressing M (2 seconds). You will then have full access to other NORM surface modes and displays. • Press L (< 2 seconds) to access Log and History. • Depress L (2 seconds) to activate the Backlight. • Press A (< 2 seconds) to access Plan, Fly, and Desat. • Depress A (2 seconds) to access ALT and Secondary. • Depress A & S (2 seconds) to access Set Modes. • Press M (< 2 seconds) to access Watch Default Time.

UPLOADING SETTINGS AND DOWNLOADING DATA The Duo Advance is configured with a Data Port located on the back of the left side that enables it to be connected to a PC through a USB port using a special Interface Cable. A USB Driver is provided on the program CD as part of the Interface System. The Settings Upload portion of the PC Interface program can be used to set/ change the Main Time, Date, Set A group (Alarms), and Set U group (Utilities) using the same Interface System. The Set F group (FO2) and FREE Mode Alarms must be entered using the button controls. Information available for retrieval (DownLoad) to the PC program includes dive number, surface interval time, maximum depth, elapsed dive time, start date, start time, lowest temperature under water, sampling rate, dive profile, settings, NIBG, O2BG, and FO2. The Duo Advance checks for the presence of an interface device connection to the Data Port once every second while in Watch Default Time Mode. Checks are not made if the Wet Activation contacts are wet. Upon sensing an interface connection, the requesting device (PC) connects to the Duo Advance and is prepared for Upload of settings or Download of data which is then initiated using the PC programs. Prior to attempting to Download data from your Duo Advance or Upload settings to it, review the HELP section of the interface program. Recommended is to print those sections of HELP that you consider appropriate for your Interface activities. 114
PC compatibility requirements: • IBM®, or compatible, Personal Computer with USB Port • Intel® Pentium 200 MHz or better microprocessor • Microsoft® Windows® 2000, XP, Vista, or 7 • Super VGA card or compatible video Graphics adaptor (256 color or greater) with a minimum 800 X 600 pixel screen area of display settings • 64 MB of available RAM • 60 MB of available hard drive storage • Mouse, CD-ROM/DVD drive, Printer
ERROR (Reset during a dive) If for any reason, the Duo Advance shuts Off then turns On again for any reason during any Dive, the message ERR (Error) will be displayed with the Up Arrow and current Depth (Fig. 124). If this occurs, it is highly recommended that you terminate the dive and begin a safe ascent to the surface.
Fig. 124 -ERROR WHILE DIVING
Upon surfacing, and any time thereafter, when access to Dive Computer Operating Mode is attempted from Watch Mode, only the message ERR will be displayed (Fig. 125). No Dive Computer Modes/screens will be inaccessible. If this occurs, the Duo Advance must be returned to the factory for evaluation/service prior to any further use for diving activities.

ALTITUDE SENSING AND ADJUSTMENT Prior to the first dive of a series of repetitive dives, Altitude (i.e., ambient pressure) is measured upon activation of Dive Surface Mode and every 15 minutes until a dive is made or operation reverts to Watch Default Time after 2 hours. > While it is operating in Watch Modes after a dive, measurements are taken every 15 minutes during the 24 hour period after surfacing. > Measurements are only taken when the unit is dry. > Two readings are taken, the second reading 5 seconds after the first. The readings must be within 1 foot (30 cm) of each other to record that ambient pressure as the current Altitude. The mathematical model in the Duo Advance accounts for the reduced No Decompression dive time available based on National Oceanic and Atmospheric Administration (NOAA) guidelines. When diving in high altitude waters from 3,001 to 14,000 feet (916 to 4,270 meters), the Duo Advance automatically adjusts to these conditions providing corrected depth, reduced No Decompression times, and reduced oxygen accumulation times at intervals of 1,000 feet (305 meters). No adjustments are made during any time that the Wet Contacts are bridged. At an elevation of 3,001 feet (916 meters), depth calibration automatically changes from feet of seawater to feet of fresh water. This is the first adjustment to the Algorithm.
116
When the Conservative Factor feature is set On, allowable dive times are calculated based upon the next higher 3,000 foot (915 meter) Altitude. All adjustments for Altitudes greater than 11,000 feet (3,355 meters) are then made to allowable dive times for 14,000 feet (4,270 meters). If the Conservative Factor is set On while at Sea Level, calculations are based upon an Altitude of 3,000 feet. The Duo Advance will not function as a Dive Computer above 14,000 feet (4,270 meters).
